This study aimed to assess the experiences of police officers facing a public inquiry following a traumatic work-related event. Interviews of 11 officers were analyzed for qualitative themes. Quantitative measures of social support and current level of distress were compared with a sample of paramedics and firefighters matched for traumatic experiences and involvement in postmortem reviews. In response to the events leading to the inquiry, reactions consistent with posttraumatic stress were

... on. Review processes were typically prolonged. Common negative consequences included lack of professional advancement, strained family relations, and inaccurate and sensationalized media attention. An important mediating factor was the quality of organizational support. Following the inquiry, police officers rarely felt a sense of vindication and frequently reported a diminished sense of commitment to their work. In conclusion, review processes following work-related trauma have many negative consequences for police officers. Suggestions for intervention include crisis intervention services with officers, organizational development, and the enhancement of peer support programs.

Using in vitro drug sensitivity data coupled with Affymetrix microarray data, we developed gene expression signatures that predict sensitivity to individual chemotherapeutic drugs. Each signature was validated with response data from an independent set of cell line studies. We further show that many of these signatures can accurately predict clinical response in individuals treated with these drugs. Notably, signatures developed to predict response to individual agents, when combined, could

... predict response to multidrug regimens. Finally, we integrated the chemotherapy response signatures with signatures of oncogenic pathway deregulation to identify new therapeutic strategies that make use of all available drugs. The development of gene expression profiles that can predict response to commonly used cytotoxic agents provides opportunities to better use these drugs, including using them in combination with existing targeted therapies. Numerous advances have been achieved in the development, selection and application of chemotherapeutic agents, sometimes with remarkable clinical successes-as in the case of treatment for lymphomas or platinum-based therapy for testicular cancers 1 . In addition, in several instances, combination chemotherapy in the postoperative (adjuvant) setting has been curative. However, most people with advanced solid tumors will relapse and die of their disease. Moreover, administration of ineffective chemotherapy increases the probability of side effects, particularly those from cytotoxic agents, and of a consequent decrease in quality of life 1,2 . Recent work has demonstrated the value in using biomarkers to select individuals for various targeted therapeutics, including tamoxifen, trastuzumab and imatinib mesylate. In contrast, equivalent tools to select those most likely to respond to the commonly used chemotherapeutic drugs are lacking 3 . With the goal of developing genomic predictors of chemotherapy sensitivity that could direct the use of cytotoxic agents to those most likely to respond, we combined in vitro drug response data, together with microarray gene expression data, to develop models that could potentially predict responses to various cytotoxic chemotherapeutic drugs 4 . We now show that these signatures can predict clinical or pathologic response to the corresponding drugs, including combinations of drugs. We further use the ability to predict deregulated oncogenic signaling pathways in tumors to develop a strategy that identifies opportunities for combining chemotherapeutic drugs with targeted therapeutic drugs in a way that best matches the characteristics of the individual. RESULTS A gene expression-based predictor of sensitivity to docetaxel To develop predictors of cytotoxic chemotherapeutic drug response, we used an approach similar to previous work analyzing the NCI-60 panel 4 from the US National Cancer Institute (NCI). We first identified cell lines that were most resistant or sensitive to docetaxel (Fig. 1a,b) and then genes whose expression correlated most highly with drug sensitivity, and used Bayesian binary regression analysis to develop a model that differentiates a pattern of docetaxel sensitivity from that of resistance. A gene expression signature consisting of 50 genes was identified that classified cell lines on the basis of docetaxel sensitivity (Fig. 1b, right) . In addition to leave-one-out cross-validation, we used an independent dataset derived from docetaxel sensitivity assays in a series of 30 lung and ovarian cancer cell lines for further validation. The significant correlation (P o 0.01, log-rank test) between the predicted probability of sensitivity to docetaxel (in both lung and ovarian cell lines) (Fig. 1c, left) and the respective 50% inhibitory concentration (IC 50 ) for docetaxel confirmed the capacity of the docetaxel predictor to predict sensitivity to the drug in cancer cell lines ( Supplementary Fig. 1 online) . For each set of cell lines, the accuracy exceeded 80%. Finally, we made use of a second independent

Marking functionally distinct neuronal ensembles with high spatiotemporal resolution is a key challenge in systems neuroscience. We recently introduced CaMPARI, an engineered fluorescent protein whose green-to-red photoconversion depends on simultaneous light exposure and elevated calcium, which enabled marking active neuronal populations with single-cell and subsecond resolution. However, CaMPARI (CaMPARI1) has several drawbacks, including background photoconversion in low calcium, slow

... s and reduced fluorescence after chemical fixation. In this work, we develop CaMPARI2, an improved sensor with brighter green and red fluorescence, faster calcium unbinding kinetics and decreased photoconversion in low calcium conditions. We demonstrate the improved performance of CaMPARI2 in mammalian neurons and in vivo in larval zebrafish brain and mouse visual cortex. Additionally, we herein develop an immunohistochemical detection method for specific labeling of the photoconverted red form of CaMPARI. The anti-CaMPARI-red antibody provides strong labeling that is selective for photoconverted CaMPARI in activated neurons in rodent brain tissue.

Current therapeutic options for cryptococcal meningitis are limited by toxicity, global supply, and emergence of resistance. There is an urgent need to develop additional antifungal agents that are fungicidal within the central nervous system and preferably orally bioavailable. The benzimidazoles have broad-spectrum antiparasitic activity but also have in vitro antifungal activity that includes Cryptococcus neoformans . Flubendazole (a benzimidazole) has been reformulated by Janssen

... a as an amorphous solid drug nanodispersion to develop an orally bioavailable medicine for the treatment of neglected tropical diseases such as onchocerciasis. We investigated the in vitro activity, the structure-activity-relationships, and both in vitro and in vivo pharmacodynamics of flubendazole for cryptococcal meningitis. Flubendazole has potent in vitro activity against Cryptococcus neoformans , with a modal MIC of 0.125 mg/liter using European Committee on Antimicrobial Susceptibility Testing (EUCAST) methodology. Computer models provided an insight into the residues responsible for the binding of flubendazole to cryptococcal β-tubulin. Rapid fungicidal activity was evident in a hollow-fiber infection model of cryptococcal meningitis. The solid drug nanodispersion was orally bioavailable in mice with higher drug exposure in the cerebrum. The maximal dose of flubendazole (12 mg/kg of body weight/day) orally resulted in an ∼2 log 10 CFU/g reduction in fungal burden compared with that in vehicle-treated controls. Flubendazole was orally bioavailable in rabbits, but there were no quantifiable drug concentrations in the cerebrospinal fluid (CSF) or cerebrum and no antifungal activity was demonstrated in either CSF or cerebrum. These studies provide evidence for the further study and development of the benzimidazole scaffold for the treatment of cryptococcal meningitis.

Although aromatase inhibitors are standard endocrine therapy for postmenopausal women with early-stage metastatic estrogen-dependent breast cancer, they are limited by the development of drug resistance. A better understanding of this process is critical towards designing novel strategies for disease management.

... ransition (EMT). Letrozole-resistant breast cancer cells (LTLT-Ca) were treated with a novel phytoalexin, glyceollin I, and exhibited morphological characteristics synonymous with an epithelial phenotype and decreased proliferation. Letrozole-resistance increased Zinc Finger E-Box Binding Homeobox 1 (ZEB1) expression (4.51-fold), while glyceollin I treatment caused á 3.39-fold reduction. Immunofluorescence analyses resulted of glyceollin I-induced increase and decrease in E-cadherin and ZEB1, respectively. In vivo studies performed in ovariectomized, female nude mice indicated that glyceollin treated tumors stained weakly for ZEB1 and N-cadherin and strongly for E-cadherin. Compared to letrozole-sensitive cells, LTLT-Ca cells displayed enhanced motility, however in the presence of glyceollin I, exhibited a 68% and 83% decrease in invasion and migration, respectively. These effects of glyceollin I were mediated in part by inhibition of ZEB1, thus indicating therapeutic potential of glyceollin I in targeting EMT in letrozole resistant breast cancer.

Further, the Symposium sought to increase awareness and thus emphasize the importance of preventing the formation of incisional and enterostomal hernias. ARTICLE IN PRESS Epidemiology, pathogenesis & economics of incisional hernias Although the overall epidemiology of incisional hernias has been well delineated, the fundamental pathogenesis of this postoperative complication and how to identify patients at increased risk remain topics of active interest and research. Furthermore, the substantial economic impact of the condition, estimated to be > $3 billion annually in the US, is garnering more attention. A systematic review of factors affecting midline incisional hernia rates A comprehensive review of the literature, including the largest meta-regression analysis published to date on the subject, identified several factors that independently increased the risk of midline incisional hernia. The factors included increasing age, obesity (or upper midline incision alone), abdominal aortic aneurysm surgery, previous laparotomy, and previous incisional hernia repair. 1 Notably, there was no evidence that suture type (absorbable vs nonabsorbable) affects the rate of hernia formation. The overall pooled incidence of incisional hernias of midline wounds at 2 years was 12.8% with a wide range (0% -36%).

... military personnel, were utilized. Service members were enrolled in the cohort in 2001, 2004, and 2007. A total of 80,106 active-duty personnel were followed over 1 year for the development of patellar tendinopathy, Achilles tendinopathy, and plantar fasciitis. Regression analyses were used to estimate significant associations between each tendinopathy, plantar fasciitis, and demographic, behavioral, and occupational characteristics. Results: Using medical records, 450 cases of Achilles tendinitis, 584 cases of patellar tendinopathy, and 1228 cases of plantar fasciitis were identified. Recent deployment was associated with an increased risk for developing plantar fasciitis (adjusted odds ratio [AOR], 1.27; 95% confidence interval [CI], 1.04-1.56). Moderate weekly alcohol consumption was marginally associated with an increased risk for Achilles tendinopathy (AOR, 1.33; 95% CI, 1.00-1.76). Overweight or obese individuals were more likely to develop Achilles tendinopathy and plantar fasciitis. Conclusion: Lower extremity tendinopathies and plantar fasciitis are common among military service members, and this study identified several modifiable risk factors for their occurrence. These potential risk factors could serve as the focus for future preventive and intervention studies.
